Small-scale biomass-based cogeneration has the potential to contribute significantly to a clean, flexible, secure, and cost-efficient energy system. It provides flexibility to future energy systems by balancing variable intermittent renewable energy sources. A smart control unit is needed to exploit its flexibility. A dynamic system model is required to enable smart control of a cogeneration unit and to determine its optimal working points. This study aims to develop, parameterise and tune a dynamic model of a cogeneration plant fuelled with fast-pyrolysis bio-oil. The system is a hybrid diesel generator/flue gas boiler plant for electricity generation and water/space heating. The plant has two unique features: (i) pyrolysis bio-oil is the new fuel for both engine and boiler and influences their operation and emissions, (ii) power and heat generation are partially decoupled and hence nonlinearly correlated. The paper presents the integration of the components ' dynamic models into a system model. The model is parameterised and partially validated using measurements from a turbocharged four-cylinder diesel engine and a swirl burner, both running on fast-pyrolysis bio-oil. Preliminary controls are designed and evaluated. The applicability and usefulness of the model for cogeneration system analysis and control design evaluation are also illustrated. Results show that the feasible operation region area of the hybrid engine/boiler system is 100% larger than that of the CHP engine. The hybrid plant can achieve energy efficiencies above 85% in response to fluctuating load demand of a hospital.

Circular economy in Architecture, Engineering, and Construction requires consideration in the design, deconstruction-planning, and waste management. This paper aims to develop a Framework to evaluate the material sustainability of buildings by comparing the proportionality of costs to environmental impacts of construction waste flows. Therefore, an extensive literature review was conducted to find parameters needed, such as building certification, life cycle assessment, or material passports. Next, a distillation process was conducted to reduce the large number of parameters found to be manageable. Following the applicable legislation, procedures to be carried out at different stages, from dismantling to recycling or treatment, were defined. Practical applications were derived, such as support for deconstruction management, resource management, and conclusions for planning. The final parameters were assigned to these processes. Due to a lack of data, data collection and public data provision are essential for applicability.

This paper aims to offer an overview of the features in the existing state of research on blockchains in the circular economy. A total of 79 articles published up to 31 May 2022 have been extracted from Scopus and Web of Science. The research design has enabled us to identify what characterises the present state of research on the use of blockchains in the circular economy. It has also allowed us to obtain a new categorisation scheme of the research that has identified five themes and the contributions in each theme and has allowed us to highlight several research gaps. The review findings indicate that the literature revolved around five research themes, namely, the relationship between blockchains and Industry 4.0, the potential of blockchains for circular economy practices, the role of blockchains in energy management, the role of blockchains in waste management and the impact of blockchains on sustainability. This review suggests several future research opportunities and provides practical implications for researchers and practitioners. To the authors' best knowledge, this study represents one of the first attempts to investigate the interplay between blockchain technology and the circular economy.

Solar energy is a promising alternative for reducing the consumption of fossil fuels. However, solar potential depends on several atmospheric parameters. When no clouds are present, aerosols are the primary source of solar radiation attenuation. This study examines the impact of aerosol optical depth on the attenuation of solar irradiance under clear sky conditions. For this purpose, aerosol data from satellite databases and irradiance data from high-performance meteorological stations installed in two sites in Morocco were exploited. Under clear sky conditions, the results showed a decrease in global horizontal irradiance relative to the global irradiance at the top of the atmosphere of 24% for aerosol optical depth values of 0.02 and exceeding 53% for 0.6. Aerosols have a more significant impact on the direct normal irradiance under clear sky conditions; over the test data, a decrease of 66% was observed for the direct normal irradiance according to the extraterrestrial irradiance for aerosol optical depth of 0.2 and reaching 92% for 0.6.

This work investigates bioethanol production from wastepaper via acid and enzymatic hydrolysis, intending to attain the highest possible yield, including an evaluation of energy consumption of the production processes and costs involved. A mathematical model was designed using MATLAB software, in which pre-calculated chronological stages have been specified with the parameters that significantly affect the bioethanol yield, including type and number of consumables, reaction temperature and residence time. The independent variables have been decided based on recommended values found in the literature and are provided as suggestions. A user is also given the choice to input the values manually. Mass and energy balance are carried out for each process stage of bioethanol production to calculate the energy consumption of the chemical reactions. The model also calculates the bioethanol yield per 100 g of lignocellulosic biomass and the related costs. A comparison between enzymatic and acid hydrolysis bioethanol is presented by a line chart on the software interface, helping the understanding of the effects of the independent variable parameters. As a result, the optimal conditions to produce the highest bioethanol yield and therefore increase the efficiency of a process are obtained. The model is expected to aid in reducing laboratory-based experiments, saving time, human errors, costly microorganisms, and other consumables.
